        Speed up sorting of <type>uuid</>, <type>bytea</>,
        and <type>char(n)</> fields by using <quote>abbreviated</> keys
        (Peter Geoghegan)
       </para>

       <para>
        Support for abbreviated keys has also been added to the non-default
        operator classes <literal>text_pattern_ops</>,
        <literal>varchar_pattern_ops</>, and <literal>bpchar_pattern_ops</>.
        Processing of ordered-set aggregates can also now exploit
        abbreviated keys.
       </para>
      </listitem>

Is it really sensible to group f1f5ec1ef together with the others?  I
think that one should be its own entry.
